Background technology
Polystyrene film is a kind of novel green wrapping material that development in recent years is got up, the polyethylene, the polyvinyl chloride film etc. that use compared with tradition, it has that intensity is high, rigidity is large, nontoxicity, easily degraded, easy coloring, have good glossiness and transparency, the advantage such as easy to process, be widely used in all kinds of article if artwork, daily necessities, metal products are particularly in the packaging of food.Developed countries at present, as the biaxially oriented polystyrene film consumption of the U.S., Canada, Japan etc., oneself accounts for the more than 60% of all film classes.
But, there are many weak points in common polystyrene material, as low in fragility, shock strength, be prone to cracking, fire-retardant fireproof is poor, weathering resistance is bad, heat-drawn wire is low etc., and because the current control temperature generally adopting in process of production makes the polystyrene film thickness produced excessive, can not meet the day by day wide application demand of client, these shortcomings have all limited the range of application of polystyrene greatly.
Thereby, need not reduce under the prerequisite of polystyrene material physical properties at present, need badly to material produce technique improve to obtain that thinness controllability is strong, good toughness, polystyrene sheet material that transmittance is high, meet the current market requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high light transmittance, high-impact polystyrene sheet material and manufacture method thereof, improves its resistance to impact shock and light transmission.
For solving the problems of the technologies described above, the object of the invention is to be achieved through the following technical solutions.
A kind of high light transmittance, high-impact polystyrene sheet material, its composition is (%) by weight ratio:
General Purpose Polystyrenre 70%;
High-impact polystyrene 30%.
A manufacture method for high light transmittance described above, high-impact polystyrene sheet material, comprises step:

(3) melts is sent into die head and extrude, cast sheet, in die head, temperature is controlled between 200 DEG C to 250 DEG C;
(4) sheet is first carried out to preheating on vertical drawing machine, carry out longitudinal stretching and sizing simultaneously; On horizontal drawing machine, carry out again preheating, carry out cross directional stretch and sizing simultaneously, obtain thin slice;
(5) described thin slice is carried out to deburring and thickness measuring, single-side/double-side is coated with silicone oil, after rolling, ageing treatment, cuts.
Preferably, between described step (1) and (2), also comprise step: described mixture is dropped into blower fan hopper, blow to moisture eliminator and carry out drying treatment through roots blower.
Preferably, in described step (3), by vacuum pump, mixture after treatment drying is drawn to the hopper of forcing machine.
Preferably, the preheating temperature of described vertical drawing machine is controlled between 50 DEG C to 150 DEG C.
Preferably, the preheating temperature of described horizontal drawing machine is controlled between 100 DEG C to 150 DEG C.
The present invention has following beneficial effect:
The present invention has improved the resistance to impact shock of sheet material by having increased HIPS; By the reasonable control of the melt temperature to forcing machine, die head temperature and longitudinal stretching speed, even thickness and the thinness of having guaranteed the polystyrene sheet material of producing are controlled, and sheet material transmittance provided by the invention is high, easily stacking, the packaging that can be widely used in the products such as food, medicine, electronics, clothes, toy, has met the market requirement greatly.
